The objectives of this study are: to assess the reliability of a method fatigue resistance assessment with elastic tube in two areas, inter and intra-examiner; check test reproducibility at different times with the same participant and compare this method with the gold standard of evaluation, the isokinetic dynamometer and compare the strength gains and endurance after the application of specific training in the elastic tube and an isokinetic dynamometer. It is a study of reproducibility, followed by application of a training protocol featuring a clinical trial.
